Psychosocial predictors of depressive symptomatology level in postpartum women

Risk factors associated with postpartum depression in a high-risk maternity clinic: a cross-sectional study

BACKGROUND

The aim of this study was to evaluate obstetric, epidemiological and social factors related to postpartum depression (PPD) and investigate possible risk factors related to this disorder, in puerperal women who had their childbirth and were referred to the High-Risk Outpatient Clinic.

METHODS

A cross-sectional study from August-December/2019 was carried out. One hundred seventy-one puerperal women were analyzed by filling out an epidemiological questionnaire and the Edinburgh Postpartum Depression Scale (EPDS) Form. Scores ≥10 were considered positive. Research on risk factors for postpartum depression was carried out.

RESULTS

29.8% of mothers had a score related with PPD. Breastfeeding without complication is protective against PPD (P=0.002 and χ²=12.533). In contrast, not having a planned pregnancy (P=0.0175, χ²=5.717), having depression at any stage of life (P=0.013, χ²=6.237), depression during pregnancy (P≤0.0001, χ²=46.201) or having a family history of depression (P=0.001, χ²=10.527), are factors associated with the development of PPD. Moreover, just having depression during pregnancy was found to be a significant risk factor for the occurrence of PPD, increasing the risk of developing this pathology by 12 times (OR=12.891).

CONCLUSIONS

Depression during pregnancy is an important risk factor for the development of PPD. This can easily be detected using the Edinburgh Postpartum Depression Scale and treated in a timely manner.

The Impact of a Mindfulness App on Postnatal Distress

Objectives

The present study investigated the effectiveness of an 8-week mindfulness mobile phone app on women’s depression, anxiety, stress and mindful attention/awareness in the postnatal period.

Methods

The study enrolled 99 mothers of a child under 1 year old, and randomly assigned them to intervention (n = 49, mean age = 31.11, SD = 4.30, years) and control (n = 50, mean age = 31.35, SD = 5.29, years) groups. Multiple regression examined intervention effects on depression, anxiety, stress and mindful attention/awareness measured post-intervention and at 4-week follow-up, controlling for the baseline and post-intervention measurement of the specific outcome, respectively.

Results

The intervention group showed significant decreases in depression, anxiety and stress levels and an increase of mindful attention/awareness post-intervention compared to the control group, with medium to large effect sizes after controlling for effects of corresponding variables at baseline. The intervention group showed further decrease in depression and stress levels and an increase in mindful attention/awareness at 4 weeks post-intervention compared to the control group, with small to medium effect sizes, after controlling for effects of corresponding variables at post-intervention.

Conclusions

The outcomes of the study suggest that delivery of mindfulness via smartphones could be a viable and affordable resource for reducing postnatal depression, anxiety and stress.

Risk factors for postpartum depressive symptoms among mothers of Colorado-born preterm infants

OBJECTIVE

Identify risk factors of postpartum depressive symptoms (PDS) among preterm infants' mothers.

STUDY DESIGN

Retrospective cross-sectional analysis of Colorado's Pregnancy Risk Assessment Monitoring System from 2012 to 2018 included weighted n = 33,633 mothers of preterm infants. Multivariate regression models calculated adjusted risk factors of PDS.

RESULTS

PDS risk factors include history of maternal depression (adjusted risk ratio [aRR] 1.98, 95% confidence interval [CI] 1.28-3.05), early preterm birth <34wga (aRR 1.48, 95% CI 1.05-2.08), no prenatal care (aRR 3.19, 95% CI 1.52-6.71), non-Hispanic other (Asian/Pacific Islander, American Indian/Alaskan, or mixed) race/ethnicity (aRR 1.76, 95% CI 1.10-2.82), and pre-pregnancy public insurance (aRR 2.34, 95% CI 1.46-3.76).

CONCLUSION

PDS risk factors among Colorado mothers of preterm infants slightly differ from identified risk factors among mothers of term infants. These findings can improve PDS screening and diagnosis so effective therapies and support can be offered during and after NICU hospitalization.

Genetic Polymorphism of rs13306146 Affects α2AAR Expression and Associated With Postpartum Depressive Symptoms in Chinese Women Who Received Cesarean Section

Postpartum depressive symptom (PDS) is a common psychological and mental disorder after giving birth. Our previous studies showing the application of dexmedetomidine, an α₂-AR agonist, can significantly improve maternal sleep, as well as relieve and reduce the incidence of PDS. This study investigated the association between α_{2 A} AR gene polymorphisms and PDS. A total of 568 cesarean section patients were enrolled; the incidence of PDS is 18.13% (103 with PDS, 465 with non-PDS). The Edinburgh Postpartum Depression Scale score ≥10 was used to diagnose PDS at 42 days after delivery. The single-nucleotide polymorphisms of α_2AR were sequenced by pyrosequencing. The effect of rs13306146 A > G polymorphism on α_2AR transcription and the regulation of miR-646 on α_2AR expression were assessed by dual luciferase reporter assays or gene transfection. Increased stress during pregnancy, poor relationship between mother-in-law and daughter-in-law, spousal relationship, domestic violence, antenatal depression, self-harm ideation, and stressful life events were all associated with increased PDS incidence (p < 0.05). The logistic regression analysis found that the α_2AAR rs13306146 polymorphism was associated with PDS after adjusting confounding variables. The transcriptional function of the α_2AAR rs13306146 A allele was decreased compared with the G allele, and the α_2AAR expression level was correspondingly decreased (p < 0.05), as the strongest binding ability of miR-646 to the α_2AAR rs13306146 AA genotype. The effect of α_2AAR rs13306146 A > G polymorphism may change the binding ability of miR-646 at the 3'UTR of the α_2AAR gene, affecting the expression of α_2AAR. This study supports the involvement of the norepinephrine system in the pathogenesis of PDS. Genotypes of α_2AAR may be novel and useful biomarkers for PDS.

Perinatal depression prevention through the mother-infant dyad: The role of maternal childhood maltreatment

BACKGROUND

Prevention studies for perinatal depression rarely focus on the mother-infant dyad or consider the impact of maternal childhood maltreatment (CM).

METHODS

A secondary analysis of two combined randomized controlled trials of Practical Resources for Effective Postpartum Parenting (PREPP) examined the moderating role of CM on the efficacy of preventing perinatal depression and effects on infant behavior at six weeks.

RESULTS

32% of 109 pregnant women endorsed CM (CM+). At six weeks postpartum, women who received PREPP compared to enhanced treatment as usual (ETAU) had significant reductions in depression and anxiety based on the observer-rated Hamilton Rating Scale for Depression (HRSD) and Hamilton Rating Scale for Anxiety (HRSA) (mean difference of M=-3.84 (SD= 0.14, p<0.01) and M=- 4.31 (SD= 0.32, p <0.001) respectively). When CM was added to the models, there no longer was a significant PREPP versus ETAU treatment effect on HRSD and HRSA outcomes in CM+ women though effects remained for CM- women. However, CM+ women who received PREPP vs ETAU reported a mean increase in infant daytime sleep of 189.8 min (SE= 50.48, p = 0.001).

LIMITATIONS

Self-report measures of infant behavior were used.

CONCLUSIONS

CM+ women versus CM- had limited response to an intervention to prevent perinatal depression yet still reported an increase in infant daytime sleep. This study adds to the growing literature that prevention studies may need to incorporate approaches tailored to fit women with childhood trauma histories while also considering infant functioning as both may be treatment targets relevant to maternal mood.

Effect of Fathers' Presence and Involvement in Newborn Care in the NICU on Mothers' Symptoms of Postpartum Depression

OBJECTIVE

To determine the prevalence of symptoms of postpartum depression (PPD) and examine how fathers' presence and involvement in the care of their newborns affect symptoms of PPD within the first 2 weeks after birth among mothers with newborns in the NICU.

DESIGN

Observational cohort study.

SETTING

Open-bay, 40-bed, tertiary level NICU in Eastern Canada.

PARTICIPANTS

Mothers (N = 105) of newborns who were anticipated to survive and required more than 5 days of hospitalization in the NICU.

METHODS

Participants completed the Postpartum Depression Screening Scale (PDSS) 14 days after they gave birth. They kept daily diaries to record the amount of time that fathers spent by the newborns' bedsides (i.e., presence) and actively caring for their newborns (i.e., involvement such as skin to skin). Participants completed daily diaries from the time of enrollment in the study until their newborns were discharged home. We analyzed the data using linear regression; score on the PDSS was the dependent variable, and fathers' presence and involvement were the independent variables. We adjusted for covariates.

RESULTS

The prevalence of positive screening for symptoms of major PPD was 24.1% (n = 20), and the prevalence of significant symptoms of PPD was 27.7% (n = 23). Participants reported that fathers were present in the NICU an average of 3.8 hours per day and were actively involved with their newborns 53% of the time. Fathers' involvement was significantly associated with lower scores on the PDSS (adjusted β = -3.85; 95% confidence interval [CI] [-6.10, -1.60]). A history of anxiety was significantly associated with greater scores on the PDSS (adjusted β = 12.06, 95% CI [2.07, 22.05]). Maternal age and income less than $50,000 CAD were marginally associated with greater scores on the PDSS (adjusted β = -0.86, 95% CI [-1.77, 0.05] and adjusted β = 10.69, 95% CI [-0.73, 22.11], respectively). The overall explained variance in the PDSS scores with the independent variables was R² = 0.35.

CONCLUSION

Fathers' involvement in the care of their newborns in the NICU was significantly associated with fewer symptoms of PPD among mothers. We recommend research with targeted interventions to promote fathers' involvement in the NICU to potentially mitigate the symptoms of PPD among mothers of newborns in the NICU.

Prevalence and risk factors of postpartum depression, general depressive symptoms, anxiety and stress (PODSAS) among mothers during their 4-week postnatal follow-up in five public health clinics in Perak: A study protocol for a cross-sectional study

INTRODUCTION

Postpartum depression, general depressive symptoms, anxiety and stress (PODSAS) are often overlooked, and may cause morbidity to new mothers, their babies and families. This study aims to determine the point prevalence of depression (post partum and general), anxiety and stress among mothers in five public health clinics in Perak at 4 weeks postdelivery and identify their associated risk factors. Findings from this study will be used to identify the needs for early screening and detection, encourage development of interventions to reduce its occurrence and support mothers with PODSAS.

METHODS AND ANALYSIS

This cross-sectional study will recruit 459 postpartum mothers during their 4-week postnatal follow-up in five selected public health clinics in Perak from September 2019 to May 2020. Participants will be mothers aged 18 years and above at 4 weeks postdelivery who are able to understand the English and Malay languages. Non-Malaysians and mothers with known diagnosis of psychotic disorders will be excluded from the study. Sociodemographic information and possible risk factors of the participants will be captured via a set of validated questionnaires, postpartum depression (PPD) will be measured using the Edinburgh Postpartum Depression Scale questionnaire and general depressive symptoms, anxiety and stress will be measured using the 21-item Depression, Anxiety and Stress Scale. Data analysis will be conducted using SPSS V.25.0 (IBM). Besides descriptive statistics, multivariable regression analyses will be done to identify possible risk factors and their independent associations with depression (PPD and general depressive symptoms, combined and separately), anxiety and stress.

ETHICS AND DISSEMINATION

The study protocol was reviewed and approved by the Medical Research Ethics Committee, Ministry of Health Malaysia on 7 August 2019. Results of this study will be reported and shared with the local health stakeholders and disseminated through conference proceedings and journal publications.

REGISTRATION NUMBER

This study is registered in the Malaysian National Medical Research Register with the ID: NMRR-19-868-47647.

Correlations Between SIRT Genetic Polymorphisms and Postpartum Depressive Symptoms in Chinese Parturients Who Had Undergone Cesarean Section

OBJECTIVE

To investigate the association of genetic polymorphisms of SIRT with postpartum depressive symptoms and analyze the risk factors for postpartum depressive symptoms in women following cesarean section.

METHODS

A total of 368 Chinese woman undergoing cesarean section were enrolled in this study. A cutoff of ≥10 for the Edinburgh Postnatal Depression Scale identified postpartum depressive symptoms. Genotypes of SIRT1, SIRT 2, and SIRT 6 were determined using Sequenom MassArray single-nucleotide polymorphism (SNP) analysis. We analyzed the contribution of genetic factors (SNPs, linkage disequilibrium, and haplotype) to postpartum depressive symptoms and performed logistic regression analysis to identify all potential risk factors for postpartum depressive symptoms and define interactions between genetic and environmental factors.

RESULTS

The incidence of postpartum depressive symptoms was 18.7% in this cohort. Univariate analysis suggested that SIRT2 polymorphism at rs2873703 (TT genotype) and rs4801933 ((TT genotype) and SIRT6 polymorphism at rs350846 (CC genotype) and rs107251 (TT genotype) were significantly correlated with the occurrence of postpartum depressive symptoms (p<0.05). Linkage disequilibrium was identified between SIRT6 polymorphisms rs350846 and rs107251. Incidence of postpartum depressive symptoms in cesarean-section parturients with SIRT2 haplotype CCC was decreased (OR 0.407, 95% CI 0.191-0.867; p=0.016). SIRT2 polymorphisms rs2873703 and rs4801933 were multiply collinear. Logistic regression analysis showed that SIRT2 polymorphism at rs2873703 (TT genotype) and rs4801933 (TT genotype), domestic violence, stress during pregnancy, and depressive prenatal mood were risk factors for postpartum depressive symptoms (p<0.05).

CONCLUSION

Pregnant women with SIRT2 genotypes rs2873703 TT and rs4801933 TT and experiencing domestic violence, stress during pregnancy, and prenatal depression are more likely to suffer from postpartum depressive symptoms.

[Premature birth: a risk factor for maternal depression?]

Premature birth constitutes a major ordeal not only for the child but also the mother. It reveals the psychological capacities of mothers with depressive affects as signs. Hedi Chaker university hospital in Sfax in Tunisia carried out a study on mothers of premature babies. These mothers were significantly more depressed. Certain factors appear to favour the occurrence of postnatal maternal depression and must therefore benefit from specific support.

The IDO genetic polymorphisms and postpartum depressive symptoms: an association study in Chinese parturients who underwent cesarean section

Postpartum depressive symptoms (PDS) are not an uncommon mood disorder in postpartum women. Our previous research indicated a role for increased tryptophan (TRP) metabolism along the kynurenine pathway (KP) in the pathogenesis of PDS. Accordingly, this study was going to investigate the association of indoleamine-2,3-dioxygenase (IDO, a key enzyme of KP) genetic polymorphisms with PDS. Seven hundred twenty-five women receiving cesarean section were enrolled in this study. PDS was determined by an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 13. Subsequently, 48 parturients with PDS and 48 parturients without PDS were selected for investigation of perinatal serum concentrations of TRP, kynurenine (KYN), and KYN/TRP ratio, the latter is the representative of IDO activity. In addition, seven single nucleotide polymorphisms of the IDO gene were examined. Following this genotyping, 50 parturients carrying the IDO rs10108662 AA genotype and 50 parturients carrying the IDO rs10108662 AC + CC genotype were selected for comparisons of TRP, KYN, and KYN/TRP ratio levels. This study showed the PDS incidence of 6.9% in the Chinese population, with PDS characterized by increased IDO activity (p < 0.05), versus women without PDS. We also found that the variations of IDO1 gene rs10108662 were significantly related to PDS incidence (p < 0.05). Furthermore, there was a significant difference in IDO activity between the IDO rs10108662 CA + AA, versus CC, genotypes. Our findings indicate a role of the kynurenine pathway in the development of PDS, rs10108662 genetic polymorphism resulting in changes of IDO activity might contribute to PDS pathogenesis.

Interventions to Prevent Perinatal Depression: Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Depression during pregnancy and the postpartum period is relatively common and can have adverse effects on both mother and child.

OBJECTIVE

To systematically review benefits and harms of primary care-relevant interventions to prevent perinatal depression, a major or minor depressive episode during pregnancy or up to 1 year after childbirth, to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMED (for publisher-supplied records only), PsycINFO, and the Cochrane Central Register of Controlled Trials; surveillance through December 5, 2018.

STUDY SELECTION

Randomized clinical trials (RCTs) and nonrandomized controlled intervention studies of interventions (eg, behavior-based, antidepressants, dietary supplements) to prevent perinatal depression in general populations of pregnant and postpartum individuals or in those at increased risk of perinatal depression. Large cohort studies were considered for harms of antidepressant use only.

DATA EXTRACTION AND SYNTHESIS

Two investigators independently reviewed abstracts and full-text articles and quality rated included studies. Random-effects meta-analysis was used to estimate the benefits of the interventions.

MAIN OUTCOMES AND MEASURES

Depression status; depression symptoms; maternal, infant, and child health outcomes.

RESULTS

Fifty studies (N = 22 385) that met inclusion criteria were identified. Counseling interventions were the most widely studied interventions. Compared with controls, counseling interventions were associated with a lower likelihood of onset of perinatal depression (pooled risk ratio [RR], 0.61 [95% CI, 0.47-0.78]; 17 RCTs [n = 3094]; I2 = 39.0%). The absolute difference in the risk of perinatal depression ranged from 1.3% greater reduction in the control group to 31.8% greater reduction in the intervention group. Health system interventions showed a benefit in 3 studies (n = 5321) and had a pooled effect size similar to that of the counseling interventions, but the pooled effect was not statistically significant using a method appropriate for pooling a small number of studies (restricted maximum likelihood RR, 0.58 [95% CI, 0.22-1.53]; n = 4738; I2 = 66.3%; absolute risk reduction range, -3.1% to -13.1%). None of the behavior-based interventions reported on harms directly. A smaller percentage of participants prescribed sertraline had a depression recurrence compared with those prescribed placebo (7% vs 50%, P = .04) at 20 weeks postpartum in 1 very small RCT (n = 22 analyzed) but with an increased risk of adverse effects to the mother.

CONCLUSIONS AND RELEVANCE

Counseling interventions can be effective in preventing perinatal depression, although most evidence was limited to women at increased risk for perinatal depression. A variety of other intervention approaches provided some evidence of effectiveness but lacked a robust evidence base and need further research.

Economic and Health Predictors of National Postpartum Depression Prevalence: A Systematic Review, Meta-analysis, and Meta-Regression of 291 Studies from 56 Countries

BACKGROUND

Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordingly, we conducted a meta-analysis to estimate the global and national prevalence of PPD and a meta-regression to identify economic, health, social, or policy factors associated with national PPD prevalence.

METHODS

We conducted a systematic review of all papers reporting PPD prevalence using the Edinburgh Postnatal Depression Scale. PPD prevalence and methods were extracted from each study. Random effects meta-analysis was used to estimate global and national PPD prevalence. To test for country level predictors, we drew on data from UNICEF, WHO, and the World Bank. Random effects meta-regression was used to test national predictors of PPD prevalence.

FINDINGS

291 studies of 296284 women from 56 countries were identified. The global pooled prevalence of PPD was 17.7% (95% confidence interval: 16.6-18.8%), with significant heterogeneity across nations (Q = 16,823, p = 0.000, I2 = 98%), ranging from 3% (2-5%) in Singapore to 38% (35-41%) in Chile. Nations with significantly higher rates of income inequality (R2 = 41%), maternal mortality (R2 = 19%), infant mortality (R2 = 16%), or women of childbearing age working ≥40 h a week (R2 = 31%) have higher rates of PPD. Together, these factors explain 73% of the national variation in PPD prevalence.

INTERPRETATION

The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal-child-health factors explain much of the national variation in PPD prevalence.

Maternal attachment style and depression associated with childbirth: preliminary results from a European and US cross-cultural study

Background

Insecure attachment style relates to major depression in women, but its relationship to depression associated with childbirth is largely unknown. A new UK-designed measure, the Attachment Style Interview (ASI), has potential for cross-cultural use as a risk marker for maternal disorder.

Aims

To establish the reliability of the ASI across centres, its stability over a 9-month period, and its associations with social context and majoror minor depression.

Method

The ASI was used by nine centres antenatally on 204 women, with 174 followed up 6 months postnatally. Interrater reliability was tested and the ASI was repeated on a subset of 96 women. Affective disorder was assessed by means of the Structured Clinical Interview for DSM–IV.

Results

Satisfactory interrater reliability was achieved with relatively high stability rates at follow-up. Insecure attachment related to lower social class position and more negative social context. Specific associations of avoidant attachment style (angry–dismissive or withdrawn) with antenatal disorder, and anxious style (enmeshed or fearful) with postnatal disorder were found.

Conclusions

The ASI can be used reliably in European and US centres as a measure for risk associated with childbirth. Its use will contribute to theoretically underpinned preventive action for disorders associated with childbirth.

Perinatal depression in Asian women: prevalence, associated factors, and cultural aspects

Background and Objective: Although perinatal depression is a worldwide problem, most of the studies related to this issue have been conducted in Western countries. This paper summarizes the literature on the prevalence as well as associated factors among Asian countries where the cultural attitudes, customs, and norms are considerably different from those in Western countries.

Methods: We conducted a literature search using MEDLINE (PubMed) from 1968, PsychINFO from 1970, and SCOPUS database from 1982 using keywords “depression”, “antenatal”, “antepartum”, “pregnancy”, “postnatal”, “postpartum”, “perinatal”, “after childbirth” and “Asia”. Only the articles published in English were included.

Results: The overall prevalence of depression during pregnancy and postnatal period are about 20% and 21.8%, respectively. The factors related to perinatal depression can be grouped into the following categories, individual characteristics, husband/marital relationship, pregnancy-related, infant-related, and other psychosocial issues. While there is considerable overlap between Asian and Western countries with respect to risk factors for perinatal depression, premarital pregnancy, conflict with mother in-law, and dissatisfaction with infant’s gender are more specific to Asian cultures.

Conclusions: Studies conducted in Asian countries suggest that the prevalence of perinatal depression is slightly higher than in Western countries. There are several unique culturally related issues that clinicians treating pregnant and postpartum Asian women should be aware as they contribute to an increased risk of depression in these women.

Factors associated with onset timing, symptoms, and severity of depression identified in the postpartum period

BACKGROUND

Unipolar and bipolar depression identified in the postpartum period have a heterogeneous etiology. The objectives of this study are to examine the risk factors that distinguish the timing of onset for unipolar and bipolar depression and the associations between depression onset by diagnosis, and general and atypical depressive symptoms.

METHODS

Symptoms of depression were assessed at 4- to 6-weeks postpartum by the Structured Interview Guide for the Hamilton Depression Rating Scale-Atypical Depression Symptoms in an obstetrical sample of 727 women. Data were analyzed using ANOVA, Chi-square, and linear regression.

RESULTS

Mothers with postpartum onset of depression were more likely to be older, Caucasian, educated, married/cohabitating, have one or no previous child, and have private insurance in contrast to mothers with pre-pregnancy and prenatal onset of depression. Mothers with bipolar depression were more likely to have a pre-pregnancy onset. Three general and two atypical depressive symptoms distinguished pre-pregnancy, during pregnancy, and postpartum depression onset, and the presence of agitation distinguished between unipolar and bipolar depression.

LIMITATIONS

The sample was urban, which may not be generalizable to other populations. The study was cross-sectional, which excludes potential late onset of depression (after 4-6 weeks) in the first postpartum year.

CONCLUSIONS

A collective set of factors predicted the onset of depression identified in the postpartum for mothers distinguished by episodes of unipolar versus bipolar depression, which can inform clinical interventions. Future research on the onset of major depressive episodes could inform prophylactic and early psychiatric interventions.

Intimate Partner Violence and Women's Depression Before and During Pregnancy

Depressive symptoms of 95 prenatal care patients were examined relative to thewomen's experiences of intimate partner violence. Women who were victims of psychological aggression during the year before pregnancy were not at elevated risk for depression except when the psychological aggression was very frequent. However, during pregnancy, psychological aggression was more closely tied to women's depression levels, regardless of its frequency. In addition, women who experienced any level of physical assault or sexual coercion by their intimate partners (before or during pregnancy) had higher levels of depressive symptoms compared to nonvictims.

Postpartum Practices and Depression Prevalences: Technocentric and Ethnokinship Cultural Perspectives

Reports of non-Western prevalence of postpartum depression (PPD) are highly variable. This variation may indicate that the label of PPD may be unacceptable in some groups or not used, that manifestations may vary by culture, or that cross-cultural diagnostic standards do not match Western clinical criteria. These factors complicate efforts to explore the relationship of postpartum traditional practices to PPD between Western and non-Western cultures. Although Stern and Kruckman viewed PPD as a culture-bound phenomenon of Western culture, an expanding international literature has demonstrated that PPD occurs in a variety of countries. To address these issues, the authors examined the literature to describe cultural postpartum traditions, to explore possible relationships among practices and PPD prevalence, to critique the culture-bound theory, and to discuss clinical practice implications.

Determinants of postnatal depression in rural ghana: findings from the don population based cohort study

BACKGROUND

Risk factors for postnatal depression (PND), one of the most pervasive complications of child bearing, are poorly understood in Africa. A recent systematic review of 31 studies found that the strongest predictors are social and economic disadvantage and gender-based factors; only six of these studies were community based, and almost all were in South Asia.

METHODS

Cohort study nested within 4 weekly surveillance of all women of reproductive age to identify pregnancies and collect data on births and deaths in the Kintampo Health Research Centre study area of Ghana. Women were screened for depression during pregnancy and after birth using the Patient Health Questionnaire to ascertain DSM-IV major or minor depression. Information was collected on determinants relating to the mother, birth, and baby, which were examined using logistic regression; effect sizes reported as relative risks with 95% confidence intervals.

RESULTS

Thirteen thousand nine hundred and twenty nine women were screened both during pregnancy and after birth, of whom 13,360 (95.9%) had complete data on potential determinants. Two hundred and fifty five (3.8%, 95% CI: 3.5%, 4.1%) had PND. Antenatal depression (AND) was the strongest determinant accounting for 34.4% of PND cases. Other determinants were season of delivery, peripartum/postpartum complications, newborn ill health, still birth, or neonatal death. Common determinants were observed for onset and persistent depression.

CONCLUSIONS

Although most AND resolves in this setting, more than a third of women with PND also had AND. Adverse birth- and baby-related outcomes are the other main determinants. We recommend that programs detect and treat depression during pregnancy and provide support to women with adverse birth outcomes.

The context of violent disagreements between parents: a qualitative analysis from parents' reports

Background

Intimate partner violence (IPV) is a prevalent public health problem that affects millions of families. Much of what is known about IPV comes from quantitative studies that often "count" acts of IPV without exploring in depth the circumstances surrounding the violence, thereby leaving critical questions unanswered; existing qualitative studies tend to focus solely on women’s perspectives. There is a dearth of dyadic qualitative research exploring the context of IPV in families with children, thus hindering the development of effective interventions for families experiencing IPV.

Methods

Seven heterosexual couples were recruited from a University-based family therapy clinic to participate in qualitative interviews. Couples were eligible if they had experienced severe verbal or any physical aggression during the past 4 months; had ≥ one child living in the household; were English-speaking; and were ≥ 18. Each individual was interviewed separately. Key topics explored included specific types of violence used by men and women; primary triggers and the context surrounding aggressive disagreements; degree to which the child(ren) were exposed; and perceived consequences for adults and children.

Results

All couples listed household responsibilities and parenting as key IPV triggers. Couples with infants reported that parenting disagreements were particularly heated, with women using aggression due to frustration about their partners’ lack of support. Couples also described substance use, wanting to be heard, and prior violence histories as triggers or as the background context for IPV episodes. Children were present during IPV and often intervened in conflicts involving severe violence. Parents’ perceptions of the effects of IPV on their children ranged from minimal to major emotional distress, with men describing more significant impact than women.

Conclusions

When describing acute triggers, parents most commonly mentioned that arguments were instigated by concerns about the division of household labor and parenting, a finding that may have significant implications for intervention development; this was particularly notable for parents of infants. Our findings emphasize the need for innovative programs that help parents cope with the stresses of raising a family as well as programs that directly address the consequences of IPV for children.

Postpartum depression on the neonatal intensive care unit: current perspectives

As the most common complication of childbirth affecting 10%–15% of women, postpartum depression (PPD) goes vastly undetected and untreated, inflicting long-term consequences on both mother and child. Studies consistently show that mothers of infants in the neonatal intensive care unit (NICU) experience PPD at higher rates with more elevated symptomatology than mothers of healthy infants. Although there has been increased awareness regarding the overall prevalence of PPD and recognition of the need for health care providers to address this health issue, there has not been adequate attention to PPD in the context of the NICU. This review will focus on an overview of PPD and psychological morbidities, the prevalence of PPD in mothers of infants admitted to NICU, associated risk factors, potential PPD screening measures, promising intervention programs, the role of NICU health care providers in addressing PPD in the NICU, and suggested future research directions.

Postpartum depressive symptoms across time and place: structural invariance of the Self-Reporting Questionnaire among women from the international, multi-site MAL-ED study

BACKGROUND

The Self-Reporting Questionnaire (SRQ) is a screening instrument that has been shown to be an effective measure of depression in postpartum women and is widely used in developing nations.

METHODS

The SRQ was administered to 2028 mothers from eight nations at two time points: one and six months postpartum. All data were obtained from the Interactions of Malnutrition and Enteric Infections: Consequences for Child Health and Development (MAL-ED) study. The sample included women from MAL-ED sites in Bangladesh, Brazil, India, Nepal, Pakistan, Peru, South Africa, and Tanzania. This study examined three aspects of validity of SRQ scores including (a) structural validity, (b) cross-cultural invariance, and (c) invariance over time.

RESULTS

A 16-item, one-factor structure with items reflecting somatic symptoms removed was deemed to be superior to the original structure in this postpartum population. Although differential item functioning (DIF) across sites was evident the one-factor model was a good fit to the data from seven sites, and the structure was invariant across the one- and six-month time points.

LIMITATIONS

Findings are based on data from self-report scales. No information about the clinical status of the participants was available.

CONCLUSIONS

Overall, findings support the validity of a modified model of the SRQ among postpartum women. Somatic symptoms (e.g., headaches, not sleeping well) may not reflect internalizing problems in a postpartum population. Implications for researchers and practitioners are discussed.

Reactions and attitudes to postpartal mental symptoms in a rural community

We examined the reactions of population, social and health care professionals and local politicians in the context of a narrative case of a newborn and her mother evincing postpartal mental symptoms. The results of this postal questionnaire study indicated that in assessing the urgent need for support, a significant positive association prevailed in the resident cohort with female gender, age over 50 years or being a parent. Professionals and politicians estimated that appropriate care and access to care would be obtained in the maternity and child health clinic in the local health centre. Residents would contact relatives rather than social and health care professionals. A future challenge is to promote the knowledge and sensitivity of the general population in recognizing mental symptoms in mothers with small children. Adequate information is also called for regarding local services and means of access to care.

Postpartum depression: risks, protective factors, and the couple's relationship

This study examined pregnancy risk for developing, and protective factors for preventing, Postpartum Depression (PPD). The object of this study was to (a) examine previously identified pregnancy stressors to learn which stressors put women more at risk for PPD and (b) to identify possible buffers for women who are at risk for developing PPD. A secondary data set was used for two analyses. Women were invited to participate in the study while still in the hospital, within 24-48 hours after delivery of a singleton, term (≥37 weeks) live-born infant. The data were collected in four large urban hospitals in Utah from 2005-2007. A total of 1,568 women participated in the study. Women who report experiencing less stress in their couple relationship are less likely to report PPD symptoms even when they have a personal history of depression and or PPD. The results of these analyses illustrate that a couple's relationship, depending on the stress level experienced in the relationship, can be both a risk and protective factor for pregnant women.

Stress, seizures, and hypothalamic-pituitary-adrenal axis targets for the treatment of epilepsy

Epilepsy is a heterogeneous condition with varying etiologies including genetics, infection, trauma, vascular, neoplasms, and toxic exposures. The overlap of psychiatric comorbidity adds to the challenge of optimal treatment for people with epilepsy. Seizure episodes themselves may have varying triggers; however, for decades, stress has been commonly and consistently suspected to be a trigger for seizure events. This paper explores the relationship between stress and seizures and reviews clinical data as well as animal studies that increasingly corroborate the impact of stress hormones on neuronal excitability and seizure susceptibility. The basis for enthusiasm for targeting glucocorticoid receptors for the treatment of epilepsy and the mixed results of such treatment efforts are reviewed. In addition, this paper will highlight recent findings identifying a regulatory pathway controlling the body's physiological response to stress which represents a novel therapeutic target for modulation of the hypothalamic-pituitary-adrenal (HPA) axis. Thus, the HPA axis may have important clinical implications for seizure control and imply use of anticonvulsants that influence this neuronal pathway.

Socioeconomic, psychiatric and materiality determinants and risk of postpartum depression in border city of ilam, Western iran

Background. Postpartum depression (PPD) is considered as one of the mood disturbances occurring during 2-3 months after delivery. The present study aimed to determine the prevalence of PPD and its associated risk factors in border city of Ilam, western Iran. Methods. Through a descriptive cross-sectional study in 2011, overall, 197 women who attended Obstetrics & Gynecology clinics postpartumly in the border city of Ilam, western Iran, were randomly recruited. A standard questionnaire that was completed by a trained midwife through face to face interviews was used for data gathering. Results. Mean age ± standard deviations was 27.9 ± 5.2 years. Prevalence of PPD was estimated to be 34.8% (95% CI: 27.7-41.7). A significant difference was observed among depression scores before and after delivery (P ≤ 0.001). Type of delivery (P = 0.044), low socioeconomic status (P = 0.011), and women having low educational level (P = 0.009) were the most important significant risk factors associated with PPD. The regression analysis showed that employed mothers compared to housekeepers were more at risk for PPD (adjusted OR = 2.01, 95% CI: 1.22-2.28, P = 0.003). Conclusions. Prevalence of PPD in western Iran was slightly higher than the corresponding rate from either national or international reports.

Effectiveness of antenatal emotional self-management training program in prevention of postnatal depression in Chinese women

PURPOSE

This study aimed to study the effectiveness of an emotional self-management training program to antenatal women in the prevention of postnatal depression.

DESIGN AND METHODS

The sample comprised 240 women who were at 32 weeks antenatal. They were randomly assigned into the intervention group and the control group.

FINDINGS

On completion of the program, the intervention group reported significantly lower mean Patient Health Questionnaire-9 and Edinburgh Postnatal Depression Scale scores than the control group. Fewer participants from the intervention group were diagnosed as having postnatal depression using the Structured Clinical Interview for DSM-IV.

PRACTICE IMPLICATIONS

An antenatal emotional self-management training that may lower the risk of developing postnatal depression among Chinese women is recommended.

Epidemiology of postpartum depressive symptoms among Canadian women: regional and national results from a cross-sectional survey

OBJECTIVES

To describe national and regional prevalence rates for significant depressive symptoms in women after 12 weeks during the postpartum period, and to identify predictors of postpartum depressive symptoms during this later time period.

METHODS

Data from the Maternity Experiences Survey of the Canadian Perinatal Surveillance System were analyzed. Participants completed a computer-assisted telephone interview between 5 and 14 months during the postpartum period (n = 6421). Depressive symptomatology was measured using the Edinburgh Postnatal Depression Scale (EPDS ≥ 13). Proportions and odds ratios with 95% confidence intervals were calculated using bootstrap methods to account for sample design and weighting adjustments.

RESULTS

About 8% of Canadian women exhibited depressive symptoms past 12 weeks during the postpartum period. Prevalence rates varied between regions. In multivariable analysis, previous history of depression (OR 1.87; 95% CI 1.43 to 2.45, P < 0.001), low household income (OR 1.64; 95% CI 1.27 to 2.11, P < 0.001), low postpartum social support (OR 3.95; 95% CI 2.77 to 5.62, P < 0.001), stressful life events (OR 2.43; 95% CI 1.88 to 3.15, P < 0.001), interpersonal violence (OR 1.40; 95% CI 1.04 to 1.87, P = 0.02), and poor self-perceived maternal health (OR 4.48; 95% CI 3.15 to 6.38, P < 0.001) were independently associated with postpartum depressive symptoms. Regional differences in correlates of postpartum depressive symptoms were found.

CONCLUSIONS

The finding that depression rates are elevated throughout the first postpartum year is important because of the known negative impact of postpartum depression (PPD). Targeted public health interventions may be needed to reduce the prevalence of PPD and its associated impact.

Barriers and facilitators of social supports for immigrant and refugee women coping with postpartum depression

An emerging concern for health care providers is how to assist immigrant and refugee women adapt to a new milieu and to cope with postpartum depression (PPD). Thirty women were interviewed to find out their perspective on what factors influence their help-seeking behavior and decision making about postpartum care and what strategies would be helpful in PPD prevention and treatment. Findings reveal that (a) social support networks can be supportive or nonsupportive with widespread effects on physical and psychological health and well-being; (b) cultural background and socioeconomic factors influence seeking support; (c) health care relationship was viewed a critical determinant to seek and accept help for PPD.

Hypnosis during pregnancy, childbirth, and the postnatal period for preventing postnatal depression

BACKGROUND

The morbidity caused by postnatal depression is enormous. Several psychological or psychosocial interventions have appeared to be effective for treating the disorder although they have not shown a clear benefit in preventing the development of PND. As yet however, the effectiveness of hypnosis has not been evaluated in relation to this.

OBJECTIVES

To assess the effect of hypnosis for preventing postnatal depression compared with usual antenatal, intranatal, or postnatal care.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2011).

SELECTION CRITERIA

Randomised controlled trials comparing hypnosis with usual antenatal, intranatal, or postnatal care, where the primary or secondary objective is to assess whether there is a reduced risk of developing postnatal depression.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and assessed the one included study for risk of bias. The included study did not contribute any data for analysis.

MAIN RESULTS

There was one included study (involving 63 women). However, as it did not include the outcomes of interest, no data were available for analysis for this review.

AUTHORS' CONCLUSIONS

There was no evidence available from randomised controlled trials to assess the effectiveness of hypnosis during pregnancy, childbirth, and the postnatal period for preventing postnatal depression. Evidence from randomised controlled trials is needed to evaluate the use and effects of hypnosis during the perinatal period to prevent postnatal depression. Two trials are currently underway which may provide further information in the future.

The effect of telephone-based interpersonal psychotherapy for the treatment of postpartum depression: study protocol for a randomized controlled trial

BACKGROUND

Substantial data indicate potential health consequences of untreated postpartum depression (PPD) on the mother, infant, and family. Studies have evaluated interpersonal psychotherapy (IPT) as treatment for PPD; however, the results are questionable due to methodological limitations. A comprehensive review of maternal treatment preferences suggests that mothers favor 'talking therapy' as a form of PPD treatment. Unfortunately, IPT is not widely available, especially in rural and remote areas. To improve access to care, telepsychiatry has been introduced, including the provision of therapy via the telephone.

METHODS/DESIGN

The purpose of this randomized controlled trial is to evaluate the effect of telephone-based IPT on the treatment of PPD. Stratification is based on self-reported history of depression and province. The target sample is 240 women. Currently, women from across Canada between 2 and 24 weeks postpartum are able to either self-identify as depressed and refer themselves to the trial or they may be referred by a health professional based on a score >12 on the Edinburgh Postnatal Depression Scale (EPDS). Following contact by the trial coordinator, a detailed study explanation is provided. Women who fulfill the eligibility criteria (including a positive diagnostic assessment for major depression) and consent to participate are randomized to either the control group (standard postpartum care) or intervention group (standard postpartum care plus 12 telephone-based IPT sessions within 12 to 16 weeks, provided by trained nurses). Blinded research nurses telephone participants at 12, 24, and 36 weeks post-randomization to assess for PPD and other outcomes including depressive symptomatology, anxiety, couple adjustment, attachment, and health service utilization. Results from this ongoing trial will: (1) develop the body of knowledge concerning the effect of telephone-based IPT as a treatment option for PPD; (2) advance our understanding of training nurses to deliver IPT; (3) provide an economic evaluation of an IPT intervention; (4) investigate the utility of the EPDS in general clinical practice to identify depressed mothers; and (5) present valuable information regarding PPD, along with associated couple adjustment, co-morbid anxiety and self-reported attachment among a mixed rural and urban Canadian population.

Interaction of maternal age and mode of delivery in the development of postpartum depression in Yerevan, Armenia

BACKGROUND

To investigate determinants of development of postpartum depression among women in Yerevan, Armenia.

METHOD

A case-control study of all reproductive age (18-45) women having 1-3 months old children registered in 7 Primary Health Care (PHC) facilities, in Yerevan. We used Edinburgh Postnatal Depression Scale (EPDS) and a structured questionnaire to assess possible postpartum depression status of mothers and exposure status through telephone interviews.

RESULTS

The study had a 96.7% response rate for 63 cases and 272 controls. The prevalence of possible postpartum depression was 14.4%. The risk of possible postpartum depression associated with age less than 25 years at childbirth was increased only among women who delivered their child through C-section (OR=7.8; 95% CI: 1.5-40.7). Meanwhile, this risk was much lower among women who delivered through vaginal delivery (OR=0.9; 95% CI: 0.4-1.8).

LIMITATIONS

EPDS had not been translated and validated in Armenia. Study population included only women having 1-3 months old children.

CONCLUSION

The study suggested that the effect of younger age at last childbirth on the risk of possible postpartum depression development was higher for women who gave birth through C-section compared to those with vaginal delivery. Despite the stressful and crisis conditions existing in Armenia over the past 2 decades the prevalence of possible postpartum depression does not differ much from that in other societies.

Prevalence and characteristics of postpartum depression symptomatology among Canadian women: a cross-sectional study

Background

This study aims to look at the prevalence and characteristics of postpartum depression symptomatology (PPDS) among Canadian women. Studies have found that in developed countries, 10-15% of new mothers were affected by major postpartum depression. Mothers who suffer from postpartum depression may endure difficulties regarding their ability to cope with life events, as well as negative clinical implications for maternal-infant attachment.

Methods

An analysis based on 6,421 Canadian women, who had a live birth between 2005 and 2006 and were part of the Maternity Experience Survey (MES), was performed. PPDS was measured based on the Edinburgh Postnatal Depression Scale. Various factors that assessed socio-economic status, demographic factors, and maternal characteristics were considered for the multinomial regression model.

Results

The national prevalence of minor/major and major PPDS was found to be 8.46% and 8.69% respectively. A mother's stress level during pregnancy, the availability of support after pregnancy, and a prior diagnosis of depression were the characteristics that had the strongest significant association with the development of PPDS.

Conclusions

A significant number of Canadian women experience symptoms of postpartum depression. Findings from this study may be useful to increase both the attainment of treatment and the rate at which it can be obtained among new mothers. Interventions should target those with the greatest risk of experiencing PPDS, specifically immigrant and adolescent mothers.

Partner relationship satisfaction and maternal emotional distress in early pregnancy

Background

Recognition of maternal emotional distress during pregnancy and the identification of risk factors for this distress are of considerable clinical- and public health importance. The mental health of the mother is important both for herself, and for the physical and psychological health of her children and the welfare of the family. The first aim of the present study was to identify risk factors for maternal emotional distress during pregnancy with special focus on partner relationship satisfaction. The second aim was to assess interaction effects between relationship satisfaction and the main predictors.

Methods

Pregnant women enrolled in the Norwegian Mother and Child Cohort Study (n = 51,558) completed a questionnaire with questions about maternal emotional distress, relationship satisfaction, and other risk factors. Associations between 37 predictor variables and emotional distress were estimated by multiple linear regression analysis.

Results

Relationship dissatisfaction was the strongest predictor of maternal emotional distress (β = 0.25). Other predictors were dissatisfaction at work (β = 0.11), somatic disease (β = 0.11), work related stress (β = 0.10) and maternal alcohol problems in the preceding year (β = 0.09). Relationship satisfaction appeared to buffer the effects of frequent moving, somatic disease, maternal smoking, family income, irregular working hours, dissatisfaction at work, work stress, and mother's sick leave (P < 0.05).

Conclusions

Dissatisfaction with the partner relationship is a significant predictor of maternal emotional distress in pregnancy. A good partner relationship can have a protective effect against some stressors.

Employed women with depression in Korea

Korean women have been reported to be more susceptible to depressive symptoms than men. In this study we explored the important predictors of depression among employed Korean women using modified Hauenstein's Nursing Practice Paradigm for Depressed Rural Women, focusing on the relationship of stressful life events and three resources (physiological, social, and psychological). In particular, we examined the moderating effects of resources on the stress-depression relationship among a community-based sample of employed Korean women. In this cross-sectional study, survey data were collected with 767 employed women in Korea over a 2-month period in 2006. Of these respondents, 286 depressed participants' data were analysed to test moderating effects of the three resources on depression. Our hierarchical multiple regression results revealed that stressful life events directly affected depression. However, after including the product terms of the three resources (i.e. regular exercise, self-efficacy, and closeness) and stressful life events, the main effect of stressful life events disappeared, confirming significant moderating effects of the resources. The findings would contribute to development of a body of culturally sensitive knowledge for clinical practice with depressed employed Korean women.

ACCESSIBLE SUMMARY

• This literature review on post-partum depression (PPD) presents an analysis of the literature about PPD and the positive and negative factors, which may influence immigrant and refugee women's health seeking behaviour and decision making about post-partum care. • A critical review of English language peer-reviewed publications from 1988 to 2008 was done by the researchers as part of a qualitative research study conducted in a western province of Canada. The overall goal of the study is to raise awareness and understanding of what would be helpful in meeting the mental health needs of the immigrant and refugee women during the post-partum period. • Several online databases were searched: Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, MEDLINE (Ovid), EBM Reviews - Cochrane Database of Systematic Reviews. • Review of the literature suggests: 1 Needs, issues and specific risk factors for PPD among immigrant and refugee women have been limited. 2 Descriptive accounts regarding culture and PPD are found in the literature but impact of cultural factors upon PPD has not been well studied. 3 Few studies look at how social support, gender, and larger institutions or organizational structures may affect immigrant and refugee women's help-seeking and access to mental health care services. 4 More research is needed to hear the immigrant and refugee women's ideas about their social support needs, the difficulties they experience and their preferred ways of getting help with PPD.

ABSTRACT

This review and analysis of the literature is about the phenomenon of post-partum depression (PPD) and the barriers and facilitators, which may influence immigrant and refugee women's health seeking behaviour and decision making about post-partum care. As part of a qualitative research study conducted in a western province of Canada a critical review of English language peer-reviewed publications from 1988 to 2008 was undertaken by the researchers. The overall goal of the study is to raise awareness and understanding of what would be helpful in meeting the mental health needs of the immigrant and refugee women during the post-partum period. Several online databases were searched: Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, MEDLINE (Ovid), EBM Reviews - Cochrane Database of Systematic Reviews. Findings suggest: (1) needs, issues and specific risk factors for PPD among immigrant and refugee women have been limited; (2) descriptive accounts regarding culture and PPD are found in the literature but impact of cultural factors upon PPD has not been well investigated; (3) few studies examine how social support, gender, institutional and organizational structures present barriers to the women's health seeking behaviour; and (4) additional research is required to evaluate immigrant and refugee women's perspectives about their social support needs, the barriers they experience and their preferred support interventions.

Development of a universal psycho-educational intervention to prevent common postpartum mental disorders in primiparous women: a multiple method approach

BACKGROUND

Prevention of postnatal mental disorders in women is an important component of comprehensive health service delivery because of the substantial potential benefits for population health. However, diverse approaches to prevention of postnatal depression have had limited success, possibly because anxiety and adjustment disorders are also problematic, mental health problems are multifactorially determined, and because relationships amongst psychosocial risk factors are complex and difficult to modify. The aim of this paper is to describe the development of a novel psycho-educational intervention to prevent postnatal mental disorders in mothers of firstborn infants.

METHODS

Data from a variety of sources were synthesised: a literature review summarised epidemiological evidence about neglected modifiable risk factors; clinical research evidence identified successful psychosocial treatments for postnatal mental health problems; consultations with clinicians, health professionals, policy makers and consumers informed the proposed program and psychological and health promotion theories underpinned the proposed mechanisms of effect. The intervention was pilot-tested with small groups of mothers and fathers and their first newborn infants.

RESULTS

What Were We Thinking! is a psycho-educational intervention, designed for universal implementation, that addresses heightened learning needs of parents of first newborns. It re-conceptualises mental health problems in mothers of infants as reflecting unmet needs for adaptations in the intimate partner relationship after the birth of a baby, and skills to promote settled infant behaviour. It addresses these two risk factors in half-day seminars, facilitated by trained maternal and child health nurses using non-psychiatric language, in groups of up to five couples and their four-week old infants in primary care. It is designed to promote confidence and reduce mental disorders by providing skills in sustainable sleep and settling strategies, and the re-negotiation of the unpaid household workload in non-confrontational ways. Materials include a Facilitators' Handbook, creatively designed worksheets for use in seminars, and a book for couples to take home for reference. A website provides an alternative means of access to the intervention.

CONCLUSIONS

What Were We Thinking! is a postnatal mental health intervention which has the potential to contribute to psychologically-informed routine primary postnatal health care and prevent common mental disorders in women.

Innovative psycho-educational program to prevent common postpartum mental disorders in primiparous women: a before and after controlled study

BACKGROUND

Universal interventions to prevent postnatal mental disorders in women have had limited success, perhaps because they were insufficiently theorized, not gender-informed and overlooked relevant risk factors. This study aimed to determine whether an innovative brief psycho-educational program for mothers, fathers and first newborns, which addressed salient learning needs about infant behaviour management and adjustment tasks in the intimate partner relationship, prevented postpartum mental health problems in primiparous women.

METHODS

A before and after controlled study was conducted in primary care in seven local government areas in Victoria, Australia. English-speaking couples with one-week old infants were invited consecutively to participate by the maternal and child health nurse at the universal first home visit. Two groups were recruited and followed sequentially: both completed telephone interviews at four weeks and six months postpartum and received standard health care. Intervention group participants were also invited to attend a half-day program with up to five couples and one month old infants, facilitated by trained, supervised nurses. The main outcome was any Composite International Diagnostic Interview (CIDI) diagnosis of Depression or Anxiety or Adjustment Disorder with Depressed Mood, Anxiety, or Mixed Anxiety and Depressed Mood in the first six months postpartum. Factors associated with the outcome were established by logistic regression controlling for potential confounders and analysis was by intention to treat.

RESULTS

In total 399/646 (62%) women were recruited; 210 received only standard care and 189 were also offered the intervention; 364 (91%) were retained at follow up six months postpartum. In women without a psychiatric history (232/364; 64%), 36/125 (29%) were diagnosed with Depression or Anxiety or Adjustment Disorder with Depressed Mood, Anxiety, or Mixed Anxiety and Depressed Mood in the control group, compared with 16/107 (15%) in the intervention group. In those without a psychiatric history, the adjusted odds ratio for diagnosis of a common postpartum mental disorder was 0.43 (95% CI 0.21, 0.89) in the intervention group compared to the control group.

CONCLUSIONS

A universal, brief psycho-educational group program for English-speaking first time parents and babies in primary care reduces de novo postpartum mental disorders in women. A universal approach supplemented by an additional program may improve effectiveness for women with a psychiatric history.

Differentials and income-related inequalities in maternal depression during the first two years after childbirth: birth cohort studies from Brazil and the UK

Background

Depression is a prevalent health problem among women during the childbearing years. To obtain a more accurate global picture of maternal postnatal depression, studies that explore maternal depression with comparable measurements are needed. The aims of the study are: (1) to compare the prevalence of maternal depression in the first and second year postpartum between a UK and Brazilian birth cohort study; (2) to explore the extent to which variations in the rates were explained by maternal and infant characteristics, and (3) to investigate income-related inequalities in maternal depression after childbirth in both settings.

Methods

Population-based birth cohort studies were carried out in Avon, UK in 1991 (ALSPAC) and in the city of Pelotas, Brazil in 2004, where 13 798 and 4109 women were analysed, respectively. Self-completion questionnaires were used in the ALSPAC study while questionnaires completed by interviewers were used in the Pelotas cohort study. Three repeated measures of maternal depression were obtained using the Edinburgh Postnatal Depression Scale in the first and second year after delivery in each cohort. Unadjusted and adjusted analyses were carried out. The Relative index of Inequality was used for the analysis of income-relate inequalities so that results were comparable between cohorts.

Results

At both the second and third time assessments, the likelihood of being depressed was higher among women from the Pelotas cohort study. These differences were not completely explained by differences in maternal and infant characteristics. Income-related inequalities in maternal depression after childbirth were high and of similar magnitude in both cohort studies at the three time assessments.

Conclusion

The burden of maternal depression after childbirth varies between and within populations. Strategies to reduce income-related inequalities in maternal depression should be targeted to low-income women in both developed and developing countries.

One year follow-up of post-partum-onset depression: the role of depressive symptom severity and personality disorders

OBJECTIVE

Long-term follow-up and risk factors of persistent post-partum depression (PPD) are fairly unknown compared with its prevalence in the developing countries. In this study, we did a follow-up measure of PPD and examined the factors, which were associated with PPD 1-year post-partum.

METHOD

Our sample comprised of 34 women. Depressive symptoms were assessed by the Edinburgh post-natal depression scale (EPDS) 6 weeks post-partum, and women with scores >12 on this scale was categorised as depressed. Personality disorders were determined at the same occasion by means of the Structured Clinical Interview for DSM-III-R personality disorders (SCID-II). One year post-partum EPDS was completed.

RESULTS

The rate of PPD 1-year post-partum was 32.4%, and it was unrelated to age at assessment, primiparity, number of children, employment status, economical status and educational level. Women depressed 1-year post-partum had significantly higher basal scores of EPDS and more often also a diagnosis of any axis II disorder; and specifically dependent and obsessive-compulsive personality disorders. In our sample, the predictors of 1-year post-partum PPD were having higher basal score of EPDS and the existence of a personality disorder.

CONCLUSION

This study suggests that women with PPD, scoring high in the EPDS scale 6 weeks post-partum and having a personality disorder, run a higher risk for depression at 1-year follow-up.

Dimensions of postpartum psychiatric distress: preliminary evidence for broadening clinical scope

BACKGROUND

Perinatal psychiatric disturbances afflict a significant number of women sometimes with tragic consequence. Yet, the range and characteristics of these disturbances are poorly understood. The goals of this research were to characterize a broader range of postpartum psychiatric symptoms and to identify their inherent structure using exploratory factor analysis (EFA).

METHODS

An Internet-based survey with 142 Likert-type questions, covering nine dimensions of postpartum mental health was constructed and posted on women's health websites. Data collected from 215 respondents was analyzed in three steps: (1) inter-item correlations were used to reduce the total number of variables by eliminating items that provided redundant information; (2) an EFA using a principal components extraction and VARIMAX rotation was performed and factors loading with Eigenvalues >1.0 were retained; (3) internal consistency was measured with Cronbach's alpha.

RESULTS

The 10 factors retained accounted for 58% of the variance and included: mental status (28%), psychoticism/morbid thoughts (6%), generalized anxiety (6%), panic (3%), guilt/self-criticism (3%), compulsive behavior (3%), hyper-vigilance (2%), contentment (2%), negative body-image (2%), and manic behavior (2%). There was strong (>0.8) internal consistency in all but the mania factor (0.6).

LIMITATIONS

The study was retrospective and respondent demographics were homogeneous.

CONCLUSION

Postpartum psychiatric disturbances are not limited to depressive symptoms. In the current study, cognitive difficulties, psychotic-morbid thoughts and anxiety symptoms accounted for the preponderance of variance while depressive symptoms did not form a cohesive factor and accounted for minimal variance. These results suggest postpartum screening tools should assess a broader array of symptoms.

Distinct trajectories of perinatal depressive symptomatology: evidence from growth mixture modeling

Although heterogeneity in the timing and persistence of maternal depressive symptomatology has implications for screening and treatment as well as associated maternal and child health outcomes, little is known about this variability. A prospective observational study of 1,735 low-income, multiethnic, inner-city women recruited in pregnancy from 2000 to 2002 and followed prospectively until 2004 (1 prenatal and 3 postpartum interviews) was used to determine whether distinct trajectories of depressive symptomatology can be defined from pregnancy through 2 years postpartum. Analysis was carried out through general growth mixture modeling. A model with 5 trajectory classes characterized the heterogeneity seen in the timing and magnitude of depressive symptoms among the study participants from Philadelphia, Pennsylvania. These classes included the following: 1) always or chronic depressive symptomatology (7%); 2) antepartum only (6%); 3) postpartum, which resolves after the first year postpartum (9%); 4) late, present at 25 months postpartum (7%); and 5) never having depressive symptomatology (71%). Women in these trajectory classes differed in demographic (nativity, education, race, parity) health, health behavior, and psychosocial characteristics (ambivalence about pregnancy and high objective stress). This heterogeneity should be considered in maternal depression programs. Additional research is needed to determine the association of these trajectory classes with maternal and child health outcomes.

Efficiency of a two-item pre-screen to reduce the burden of depression screening in pregnancy and postpartum: an IMPLICIT network study

OBJECTIVE

Systems for efficient case finding of women with major depression during pregnancy and postpartum are needed. Here we assess the diagnostic accuracy of a modified 2-item patient health questionnaire (PHQ-2) as a pre-screen in assessing depression.

METHODS

Cross-sectional assessments at 15 weeks' gestation (n = 414), 30 weeks' gestation (n = 334), and 6 to 16 weeks postpartum (n = 193) among women from a diverse set of races/ethnicities, participating in the IMPLICIT maternal care quality improvement network. The Edinburgh Postnatal Depression Scale score (>or=13) was used as the criterion measure for the PHQ-2.

RESULTS

A positive 2-item screen had sensitivity of 93%, 82%, and 80% and specificity of 75%, 80%, and 86% for Edinburgh Postnatal Depression Scale score of >or=13 for assessment at 15 and 30 weeks gestational age and postpartum, respectively. The positive/negative predictive values for the PHQ-2 were 44/98, 24/91, and 30/98 for each time point, respectively. Areas under the receiver operating characteristic curve analysis suggested that 2-item assessments at each time point had approximately equal diagnostic validity.

CONCLUSIONS

Two questions were efficient to rule out depression and reduced the need for further screening of approximately 60% to 80% of women, depending on the point in pregnancy or postpartum. A diagnostic interview follow-up of women screening positive is still required.

Employee entitlements during pregnancy and maternal psychological well-being

BACKGROUND

Antenatal psychological well-being is multifactorially determined, including by social circumstances. Evidence suggests that workplace conditions are salient determinants of mental health, but it is not known whether employment conditions influence antenatal psychological well-being.

AIMS

To investigate the relationship between employment conditions and antenatal psychological well-being in Australian women.

METHODS

A sociodemographically diverse consecutive cohort of employed nulliparous women was recruited in late pregnancy. Data were collected by a structured interview assessing sociodemographic characteristics, employment arrangements, experience of pregnancy-related discrimination, and access to maternity leave entitlements. Participants completed two standardised psychometric measures of maternal mood: the Edinburgh Depression Scale (EDS) and the Profile of Mood States (PoMS). Comparisons of self-reported mood were made between women by experience of workplace adversity, using a composite measure of workplace events.

RESULTS

Of 205 eligible women, 165 agreed to participate. Of these, 114 of 165 (69%) reported at least one form of workplace adversity during pregnancy. More women without private health insurance (78%) reported workplace adversity than those who were privately insured (57%) (chi2(1)=6.95, P=0.008). Women experiencing workplace adversity had significantly worse psychological well-being as indicated by the EDS score (7.7+/-5.1) than those who were experiencing no workplace adversity (5.5+/-3.4), mean difference (95% CI)=-2.2 (-3.7 to -0.8), P=0.003. Similar results were reported for the PoMS.

CONCLUSIONS

Workplace adversity during pregnancy is associated with poorer maternal psychological well-being. Workplace conditions and entitlements are salient factors for consideration in assessments of antenatal psychosocial well-being.

Psychosocial and psychological interventions for treating postpartum depression

BACKGROUND

Postpartum depression is a major health issue for many women from diverse cultures. While pharmacological interventions are an effective treatment for depression, mothers are often reluctant to take antidepressant medication due to concerns about breast milk transmission or potential side-effects. It is important that non-pharmacologic interventions be evaluated for use with postpartum women experiencing depressive symptomatology.

OBJECTIVES

Primary: to assess the effects of all psychosocial and psychological interventions compared with usual postpartum care in the reduction of depressive symptomatology.Secondary: to examine (1) the effectiveness of specific types of psychosocial interventions; (2) the effectiveness of specific types of psychological interventions; (3) the effectiveness of specific types of psychosocial interventions versus psychological interventions; (4) the effects of intervention mode (e.g., individual versus group-based interventions); and (5) the effects of sample selection criteria (e.g., targeting women with clinically diagnosed depression versus self-reported depressive symptomatology).

SEARCH STRATEGY

CCDANCTR-Studies and CCDANCTR-References were searched on 1/8/2007, the Cochrane Pregnancy and Childbirth Review Group trials register, CENTRAL, MEDLINE (1966 to 2006), EMBASE (1980 to 2006) and CINAHL (1982 to 2006) using various combinations of the terms 'postpartum/postnatal depression.' Secondary references and experts in the field were used to identify other published or unpublished trials.

SELECTION CRITERIA

All published, unpublished, and ongoing randomised controlled trials and quasi-randomised trials of psychosocial or psychological interventions where the primary or secondary aim was a reduction in depressive symptomatology.

DATA COLLECTION AND ANALYSIS

Both review authors participated in the evaluation of methodological quality and data extraction. Additional information was sought from several trial researchers. Results are presented using relative risk for categorical data and weighted mean difference for continuous data.

MAIN RESULTS

Ten trials met the inclusion criteria, of which nine trials reported outcomes for 956 women. Any psychosocial or psychological intervention, compared to usual postpartum care, was associated with a reduction in the likelihood of continued depression, however measured, at the final assessment within the first year postpartum. Both psychosocial and psychological interventions were effective in reducing depressive symptomatology. Trials selecting participants based on a clinical diagnosis of depression were just as effective in decreasing depressive symptomatology as those that enrolled women who met inclusion criteria based on self-reported depressive symptomatology.

AUTHORS' CONCLUSIONS

Although the methodological quality of the majority of trials was, in general, not strong, the meta-analysis results suggest that psychosocial and psychological interventions are an effective treatment option for women suffering from postpartum depression. The long-term effectiveness remains unclear.

Relative socioeconomic advantage and mood during advanced pregnancy in women in Vietnam

Background

Mental health during pregnancy has not been investigated in Vietnam. Antenatal depression is an established risk factor for postpartum mood disturbance and two representative cohort studies have found rates of depression after childbirth in Vietnam two to three times higher than those in high income countries.

Aim

The aim of this exploratory study was to investigate the prevalence and determinants of depression in a cohort of pregnant Vietnamese women. This was the subsidiary aim of an investigation of sexual beliefs and behaviours in pregnancy in Vietnam.

Methods

Participants were recruited from antenatal clinics at Hanoi Obstetric Hospital. Inclusion criteria were to be in advanced pregnancy and appear well educated and confident and therefore potentially be willing to discuss sexual matters. Data were collected by individual structured interviews assessing socio-demographic characteristics, reproductive health, quality of intimate relationship and adequacy of support. Emotional wellbeing was assessed by the Vietnamese translation of the Edinburgh Depression Scale (EDS).

Results

In total 61/74 (82%) of women approached to participate were recruited. The mean EDS score of 5.42 ± 3.8, was similar to that of community cohorts in high income countries and only one participant scored above 15. The cohort was relatively socioeconomically advantaged with high rates of post-secondary education, secure salaried employment, reproductive autonomy and ability to afford higher quality antenatal care. Most participants were able to confide in their husbands and their pregnancies were welcome. Worse mood was associated with insecure casual work, crowded living conditions and experiencing critical coercion in the marital relationship.

Conclusion

There is an apparently low prevalence of symptoms of depression in relatively socioeconomically advantaged pregnant women in Vietnam.
